HELP!

Period is always extremely regular, and due last Thursday, 7/2, but never did. I got what I thought was AF on Monday (7/6) and bled very light red/and brown spotting for less than a day and a half. Took a few test with VERY faint lines, and was told blue dye test are notorious for Evap lines so here's my pink dye test and some blues... What do y'all think?!!!!
